Abstract (en)
[origin: ES8605941A1] The invention relates to the freezing of biological products contained in straws and more particularly to the initiation of the crystallization phase. A series of straws is disposed in such manner that the straws are arranged in parallel side-by-side relation and a crystallization bar (10) is mounted by springs (20) on two arms (11 and 12) connected to a rotary shaft (13). The arms shift the bar between a waiting position in a receiver-cradle (16) which is deeply cooled by a pipe (17-18) and an operative position in which is bears against the straws. Application in the freezing of blood cells, human and animal sperm, fragments of biological tissues and embryos, etc.

L'invention concerne la congélation de produits biologiques conditionnés en paillettes et plus particulièrement l'initiation de la phase de cristallisation. Une série de paillettes est disposée parallèlement côte à côte et une barrette de cristallisation (10) est montée par ressort (20) sur deux bras (11 et 12) solidaires d'un arbre rotatif (13) entre une position d'attente dans un berceau-récepteur (16) refroidi profondément par une tubulure (17 - 18) et une position de travail en appui sur les paillettes. Application à la congélation de cellules sanguines, spermes humains et animaux, fragments de tissus biologiques, embryons, etc...
